Hi, I'm testing building a multiplatform library. I added the js target and a dependency to the js stdlib, but when I run the build gradle task, I get the following error:

org.gradle.execution.MultipleBuildFailures: Build completed with 1 failures.
	...
        ...
Caused by: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':modules:bitflags:compileKotlinJs'.

Here's the link to the gradle.kts file of the module I'm trying to build: https://github.com/LouisCAD/Splitties/blob/baaf3548141ac5f8e631b5f858cc9ce25bfa2cbe/modules/bitflags/build.gradle.kts#L28
and here's the buildSrc it depends on:
https://github.com/LouisCAD/Splitties/tree/baaf3548141ac5f8e631b5f858cc9ce25bfa2cbe/buildSrc
I'm using Kotlin 1.3.21 with Gradle 4.10.1, and AGP 3.3.1 for the Android part.

My JVM builds fail on that gradle version for the same reason.

On gradle 4.7, metadata feature is outdated.
On gradle 4.8 you get "Duplicate method name getExt() in AccessorsKt"
on 4.10 you get "NoSuchMethodError: createModuleFile"
on 5.1 you get "cannot change attributes of configuration ':nativeApiElements' after it has been resolved"
For me, this is the definition of "experimental"

Thanks for the link, I'll try with the suggested resolution strategy!

[louiscad]

For reference, adding the following into my `buildSrc`'s build.gradle.kts file resolved my issue:

configurations.all {
    val isKotlinCompiler = name == "embeddedKotlin" || name.startsWith("kotlin") || name.startsWith("kapt")
    if (!isKotlinCompiler) {
        resolutionStrategy.eachDependency {
            if (requested.group == "org.jetbrains.kotlin" && requested.module.name == "kotlin-compiler-embeddable") {
                useVersion("1.3.21") // Update to whatever the Kotlin version you need is
            }
        }
    }
}

why is gradle so flakey?

[Dico]

I wish I knew.

[janvladimirmostert]

every time there's a gradle update, something stops working
compare it with maven where scripts that were written years ago still continue to work years later across maven versions.
hopefully Gradle 5 doesn't change too much again

Gradle is known to break backwards compatibility often, which is a intentional part of its design unfortunately ☹️.
